Anyways, if you're saying that it's a small increase in DPS, then what's the point? The stat is still useless. You've already failed to make it of any more importance than it currently is as a defensive stat. Further, the word "Parry" makes no sense as an offensive stat.
Parry: verb: to ward off a weapon or attack.
Hence, it is a defensive stat. To try to twist it into an offensive stat is just plain idiotic. So you shouldn't just be asking SE to entirely change the mechanics of the stat, but to also change the name of the stat. Both of which are useless changes when you admit that the importance of Parry would be insignificant still. My suggestion, however, just asks SE to take the mechanic of Strength they had implemented in 2.x where it effected the strength of your Parry, and put it on Parry instead, so that your Parry stat would now effect both the rate and the strength. This would require absolutely no alteration of the stat's name, and it is using a system they have already used before, as well as follow in line with the same theme as another secondary stat that they changed with 3.0. This would also help Dark Knight by boosting the effectiveness of their Dark Dance. The stat would has slightly more importance in this manner too, and since it's heavily sunk into tanking gear, and completely devoid on other gear, it would only effect tanks themselves. Further, since it's a secondary stat that effects the strength of your parry instead of a primary stat like it use to be, building a whole lot of it would be more difficult than building just tons of strength, since you can't just stack strength trinkets to stack more parry strength, you would HAVE to use Vitality trinkets to make use of their parry secondary. There would be more incentive for tanks to be tanks, and then more tactical difficulty when deciding to drop your vit trinkets and going into strength.
